Near-infrared spectral downshifting in Sr(3−x)(VO4)2:xNd3+ phosphor
In this study, the spectral downshifting (DS) from ultraviolet (UV) light to near-infrared (NIR) radiation in Sr 3 (VO 4 ) 2 :Nd 3 + phosphor is reported. The prepared materials were characterized by X-ray powder diffraction (XRD) and photoluminescence (PL) properties along with steady state lumines...
